Given numbers are 357, 734, 990, 646

The list of prime factors of all numbers are

Prime factors of 357 are 3 x 7 x 17

Prime factors of 734 are 2 x 367

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 646 are 2 x 17 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 357, 734, 990, 646

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(357, 734) = 262038

GCD(357, 734) = ( 357 x 734 ) / 262038

= 357 / 734

= 357

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 357, 734, 990, 646 is 1
